I purchased a cultivar called "Blue Cascade." I believe it may be a somewhat more dwarf, that is, slow growing, form. The foliage is a somewhat lighter shade of blue than the typical glauca pendula. The nursery guy suggested growing in part shade, since full sun might burn and bleach this delicate color. Some sites that I trust identify its width at ten years to be about six feet.

This can be an extraordinarily beautiful tree, if well sited and well trained. It can form blue waterfalls of foliage, weeping down over a steep slope or a retaining wall, spilling over boulders, or after training up onto a pergola.

Small specimens are trained into an s-shape by the nurseries and thoughtlessly planted in huge numbers in inappropriate sites. It sometimes forms beautifully grotesque shapes when left to its own devices, but on flat ground it generally benefits from some thoughtful ongoing training, especially when young.

Intolerant of shade, wind, and poor drainage. This rarely prospers in the hot humid summers of the eastern US south of Z7.

Purchased a WEEPING BLUE ATLAS CEDAR this summer @ local nursery & planted it against sheltered SW side of house. Wondering if I should protect it with burlap?? I've seen them growing as far north as Niagara & hope it will winter here. Any comments appreciated.

I planted my blue cedar in 1987 in my back yard appoximately 10 feet in from the rear corner. Since
then I have trained it to go to the rear corner made a right turn and it has continued for another thirty five.
Going in the other direction from the trunk the plant goes
another thirty five feet toward the front of my house.
The plant is no higher then five feet over all and the hanging branches makes a gorgeous back drop for the
flower beds. I receive complements from everyone.
I have no special experience in gardening so if their
is anyone who is interested in doing the same, you can
do it.

This tree needs room to spread and can become really huge - 30 feet across. If you want it smaller, it needs special attention to training. If you have the room for it, or the willingness to keep it in line from an early age, it's an incredibly beautiful tree.
